What determines the stability of embankment and separating dams?
The stability of the embankment and separating dams of a TSF is determined by a complex of geotechnical, hydrogeological, and anthropogenic factors. The following have the greatest influence: physical and mechanical characteristics of soils and tailings (wastes); the process of construction and operation of a structure; nature of its base; hydrodynamic, hydrostatic, seismic, and dynamic forces. A structure option of the dam body at this specific section, developed on the basis of the simulation, provided a factor of safety values for the outer slope at well no. 324-19. This was FoS = 1.664 for the main combination of loads, and FoS = 1.430 for a special combination of loads under seismic action.

π₯ Ash and slag dumps β worthless waste or hidden treasure?
Did you know that ash and slag dumps may contain hundreds of tons of valuable metals? Researchers have proven: ash processing is not just about ecologyβitβs a profitable business!
What was found in the dump?
βοΈ Titanium (785 t) β for aerospace industry
βοΈ Strontium (183 t) β for electronics and medicine
βοΈ Iron (4,867 t) β for metallurgy
Why does it matter?
π± Ecology: Processing just 10% of the dumps reduces environmental harm by 20%.
π° Economics: The project pays for itself in 4 years.
How does it work?
β’ Gravity separation β sorting ash into fractions
β’ Magnetic separation β extracting metals
β’ Concentrate sales β ready-to-use industrial product
Whatβs next?
The technology is set to be implemented soon. Perhaps soon, power plant ash will be valued as highly as ore deposits!
For more information, see the article:

π¬ What do you think β are such projects worth investing in?
